LUBRlCATlNG-AXLE.

SPECIFICATION forming part of Letters Patent No. 597,910, dated January25, 1898.

Application filed August 14,1897.

To aZZ whom it may concern.-

Be it known that l, Gonnon M. MATHER, a citizen of the United States,and a resident of the city of Canton, county of Stark, State of Ohio,have invented a new and useful Improvement in Lubricating-Axles, ofwhich the following is ai'ull, clear, and exact description, referencebeing had to the accompanying drawing, making part of thisspecification.

My invention relates to an improvement in dust-protecting andlubricating axles; and it consists of the spindle proper, provided witha longitudinal groove for the purpose of carrying oil and returningspiral grooves at each end thereof, passing around thespindle andterminating at points beyond the ends of the longitudinal groove, bymeans of which the spindle and box are constantly kept lubricated andthe oil is returned to the longitudinal groove, as is hereinafter morefully described and claimed.

In the accompanying drawing similar letters of reference refer tosimilar parts.

. The figureis a side elevation of the spindle and box, with a portionof the box and axle cut away, showing the relation of the various parts.

A represents the axle proper, which terminates in a spindle a. At theend of the axle and intermediate the spindle there is formed acup-shaped projection or collar a having a tubular flange a upon theouter surface of which there is provided a circumferential groove 0. forthe purpose of preventing the passage of dust into and upon the spindle.Upon the upper portion of the spindle there is provided a longitudinalgroove of, the ends of which terminate a short distance from the innerand outer ends of the spindle. At either end-of the longitudinal groovea there are provided spiral grooves a and a, which pass clear around thespindle and terminate at points on the upper part of the spindleopposite the ends of the longitudinal groove a In the middle of thelongitudinal groove there is provided a distributing-groove a whichterminates a short distance therefrom. The

' object of these several grooves is to provide Serial No. 648,214. (Nomodel.)

small groove a carries the oil out upon the surface of the spindle,while the spiral grooves a and a at either end take up the oil andreturn it to the longitudinal groove a thus preventing the exudation ofoil at either end of the spindle.

13 represents the box, which is of tubular form, its interior adapted toconform in size to the spindle. At the inner end of the box there is araised collar carrying two tubular flanges. The inner flange Z) is onthe same plane as the interior of the box, which rests upon the spindle,and passes between the spindle and the flange 0, upon the cup-shapedportion or collar of the axle. The outer flange Z2 being longer than theinner flange, passes over the flange a and the circumferential groove aformed thereon, completely covering the same, so as to make asubstantially dust-proof connection of the box and the axle.

The outer end of the spindle is screwthreaded, so as to carry theordinary form of nut C, by means of which the box is held in engagementwith and in position upon the spindle, and upon the outer end of the boxthere is formed a raised rib 19 which when the nut Ois screwed downbecomes embedded in the Washer carried in the nut and prevents theexudation of oil or the passage of dust into and upon the spindle.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is An imperforate axle-spindle having a1ongitudinal groove which ends short of the spindle ends, adistributing-groove leading from the longitudinal groove and terminatinga short distance therefrom, and spiral grooves communicating with thelongitudinal groove near its ends, said spiral grooves extending aroundthe spindle and merging into the plane of the spindle at points beyondthe ends of the longitudinal groove, substantially as set forth.

' In testimony whereof I have hereunto set my hand this 10th day ofAugust, A. D. 1897.
